The wires are made up of one or more flexible wires with a light and soft sheath; the cables are made of one or more insulated sheathed wires and covered with a tough outer layer made of metal or rubber.
Cables and wires are generally composed of three components: a core wire, an insulating sheath, and a protective sheath.
The characteristics of commonly used cables are as follows:
CEF - Ethylene propylene rubber insulated neoprene sheathed, shipboard flame retardant power cable.
CVV - PVC insulated, PVC sheathed shipboard flame retardant power cable.
Oxygen tank wires often use BV, BX, RV, RVV series wires, including:
BV - copper core PVC insulated wire, long-term allowable temperature of 65 °C, the minimum temperature of -15 °C, the working voltage of AC 500V, DC 1000V, fixed laying in the indoor and outdoor, can also be deposited in the dark.
BX - copper core rubber insulated wire, the highest temperature of 65 °C, deposited in the room.
RV—PVC insulated single-core cord with maximum operating temperature of 65°C, minimum operating temperature of -15°C, working voltage of 250V AC, and 500V DC, used as internal wiring for instruments and equipment.
RVV - Copper core PVC insulated and sheathed flexible wire, allowing long-term working temperature of 105 °C, working voltage AC 500V, DC 1000V, used in wet, high mechanical protection requirements, often moving and bending occasions.
